Austin Mini 998, 1098, 1275 and larger*

 

Here is another innovative new product from our company. This is an Auction for a Brand-New set of 1275 cc "A-series" Roller Rockers Arms. You may also request the alternative version for the 948, 998 and 1098 cc engines.

These roller rockers fit onto the the standard  rocker shaft without any modifications to the original components. They have an a conservative 1.347 to 1 lift ratio that is more aggressive than standard (1.25:1), yet more conservative than others available elsewhere. This allows you to safely improve performance without having to rebuild the lower portion of your engine and replace the cam shaft.  You can expect smoother running and a boost of power at the wheels.

1.5:1 lift sets are available in one of our other Ebay listings. 

What we love best about this product is the overall simplicity. These roller rockers reuse all of the original rocker hardware for a lifetime of quiet, trouble free life. Simply slide them onto the original shaft in place of the old ones. You will reuse your original rocker shaft and tensioners.

Please note, that there were different size tensioners used on some A-series rocker assesmblies. Our rockers use the more common 5/16 thread pattern, so you might want to check your tensioner's thread size before assembly. New 5/16 tensioners are readily available cheaply from your usual parts sources.

Valve clearance remains set to standard. There is a heavy duty bronze bushing in the center that couples with th rocker shaft and a hardened roller on the rocker tip. You can expect an appreciable power gain with far less valve clatter. Satisfaction guaranty! Lifetime Warranty against defect!
